6b25909f6b HTTP/2 HelloWorld clear text NPE
Motivation:
HelloWorldHttp2Handler throws a NPE when converting from HTTP/1.x headers to HTTP/2 headers because there is no Host header.

Modifications:
- HelloWorldHttp2Handler should check if the Host header is present before setting it in the HTTP/2 headers

Result:
No more NPE in HelloWorldHttp2Handler.

cf26227c6c Supply a builder for Http2Codec
Motivation:

DefaultHttp2FrameWriter has constructors that it would be a hassle to
expose as configuration parameters on Http2Codec. We should instead
make a builder for Http2Codec.

Modifications:

Get rid of the public constructors on Http2Codec and instead make sure
you can always use the builder where you would have used the constructor
before.

Result:

Http2Codec can be configured more flexibly, and the SensitivityDetector
can be configured.

92efa3c916 Add UptimeServer and adjust UptimeClient's code style.
Motivation:

Uptime example is lack of server.
UptimeClient's code style is a little bit different from others, which make reader feel confused.
We don't need to create a new Bootstrap instance each time client reconnect to server.

Modification:

Add UptimeServer and UptimeServerHandler which simply accept all connection and discard all message.
Change UptimeClient's code style.
Share a single Bootstrap instance.

Result:

Uptime server support.
Consistent code style.
Single Bootstrap for all reconnection.

b1cb059540 Motivation:
It is generally useful to have origin http servers respond to
"expect: continue-100" as soon as possible but applications without a
HttpObjectAggregator in their pipelines must use boiler plate to do so.

Modifications:

Introduce the HttpServerExpectContinueHandler handler to make it easier.

Result:

Less boiler plate for http application authors.

38483e8790 Correctly manage buffer life-cycle in http2 multiplex example
Motivation:

We not correctly managed the life-cycle of the buffer / frames in our http2 multiplex example which lead to a memory leak.

Modifications:

- Correctly release frame if not echo'ed back the remote peer.
- Not retain content before echo back to remote peer.

Result:

No more leak in the example, fixes [#6636].

077a1988b9 OCSP stapling support for Netty using netty-tcnative.
https://github.com/netty/netty-tcnative/pull/215

Motivation

OCSP stapling (formally known as TLS Certificate Status Request extension) is alternative approach for checking the revocation status of X.509 Certificates. Servers can preemptively fetch the OCSP response from the CA's responder, cache it for some period of time, and pass it along during (a.k.a. staple) the TLS handshake. The client no longer has to reach out on its own to the CA to check the validity of a cetitficate. Some of the key benefits are:

1) Speed. The client doesn't have to crosscheck the certificate.
2) Efficiency. The Internet is no longer DDoS'ing the CA's OCSP responder servers.
3) Safety. Less operational dependence on the CA. Certificate owners can sustain short CA outages.
4) Privacy. The CA can lo longer track the users of a certificate.

0ee36fef00 Accept two ways to start HTTP/2 over clear text
Motivation:

HTTP/2 support two ways to start on a no-tls tcp connection,
http/1.1 upgrade and prior knowlege methodology to start HTTP/2.
Currently, the http2-server from example only support
starting by upgrade. I think we can do a simple dispatch by peek first
bytes from inbound that match to prior knowledge preface or not and
determine which handlers to set into pipeline.

Modifications:

Add ClearTextHttp2ServerUpgradeHandler to support start HTTP/2 via clear
text with two approach. And update example/http2-server to support
this functionality.

Result:

netty HTTP/2 and the example http2-server accept for two ways to start
HTTP/2 over clear text.

Fixed memory leak problem

Update fields to final

Rename ClearText to cleartext

Addressed comments for code improvement

- Always prefer static, final, and private if possible
- Add UnstableApi annotation
- Used EmbeddedChannel.readInbound instead of unhandled inbound handler
- More assertion

Update javadoc for CleartextHttp2ServerUpgradeHandler

Rename ClearTextHttp2ServerUpgradeHandler to CleartextHttp2ServerUpgradeHandler

Removed redundant code about configure pipeline

nit: PriorKnowledgeHandler

Removed Mockito.spy, investigate conn state instead

Add Http2UpgradeEvent

Check null of the constructor arguments

Rename Http2UpgradeEvent to PriorKnowledgeUpgradeEvent

Update unit test

1419f5b601 Adding support for Conscrypt (#6271)
Motivation:

Conscrypt is a Java Security provider that wraps OpenSSL (specifically BoringSSL). It's a possible alternative to Netty-tcnative that we should explore. So this commit is just to enable us to further investigate its use.

Modifications:

Modifying the SslContext creation path to support the Conscrypt provider.

Result:

Netty will support OpenSSL with conscrypt.

e13da218e9 HTTP/2 revert Http2FrameWriter throws API change
Motivation:
2fd42cfc6b fixed a bug related to encoding headers but it also introduced a throws statement onto the Http2FrameWriter methods which write headers. This throws statement makes the API more verbose and is not necessary because we can communicate the failure in the ChannelFuture that is returned by these methods.

Modifications:
- Remove throws from all Http2FrameWriter methods.

Result:
Http2FrameWriter APIs do not propagate checked exceptions.

3344cd21ac Wrap operations requiring SocketPermission with doPrivileged blocks
Motivation:

Currently Netty does not wrap socket connect, bind, or accept
operations in doPrivileged blocks. Nor does it wrap cases where a dns
lookup might happen.

This prevents an application utilizing the SecurityManager from
isolating SocketPermissions to Netty.

Modifications:

I have introduced a class (SocketUtils) that wraps operations
requiring SocketPermissions in doPrivileged blocks.

Result:

A user of Netty can grant SocketPermissions explicitly to the Netty
jar, without granting it to the rest of their application.

2fd42cfc6b HTTP/2 Max Header List Size Bug
Motivation:
If the HPACK Decoder detects that SETTINGS_MAX_HEADER_LIST_SIZE has been violated it aborts immediately and sends a RST_STREAM frame for what ever stream caused the issue. Because HPACK is stateful this means that the HPACK state may become out of sync between peers, and the issue won't be detected until the next headers frame. We should make a best effort to keep processing to keep the HPACK state in sync with our peer, or completely close the connection.
If the HPACK Encoder is configured to verify SETTINGS_MAX_HEADER_LIST_SIZE it checks the limit and encodes at the same time. This may result in modifying the HPACK local state but not sending the headers to the peer if SETTINGS_MAX_HEADER_LIST_SIZE is violated. This will also lead to an inconsistency in HPACK state that will be flagged at some later time.

Modifications:
- HPACK Decoder now has 2 levels of limits related to SETTINGS_MAX_HEADER_LIST_SIZE. The first will attempt to keep processing data and send a RST_STREAM after all data is processed. The second will send a GO_AWAY and close the entire connection.
- When the HPACK Encoder enforces SETTINGS_MAX_HEADER_LIST_SIZE it should not modify the HPACK state until the size has been checked.
- https://tools.ietf.org/html/rfc7540#section-6.5.2 states that the initial value of SETTINGS_MAX_HEADER_LIST_SIZE is "unlimited". We currently use 8k as a limit. We should honor the specifications default value so we don't unintentionally close a connection before the remote peer is aware of the local settings.
- Remove unnecessary object allocation in DefaultHttp2HeadersDecoder and DefaultHttp2HeadersEncoder.

Result:
Fixes https://github.com/netty/netty/issues/6209.

d771526f8c HTTP/2 HelloWorld Client Example Bug
Motivation:
The HTTP/2 helloworld client example has 2 bugs:
1. HttpResponseHandler has a map which is accessed from multiple threads, but the map is not thread safe.
2. Requests are flushed and maybe completely written and the responses may be received/processed by Netty before an element is inserted into the HttpResponseHandler map. This may result in an 'unexpected message' error even though the message has actually been sent.

Modifications:
- HttpResponseHandler should use a thread safe map
- Http2Client shouldn't flush until entries are added to the HttpResponseHandler map

Result:
Fixes https://github.com/netty/netty/issues/6165.

540c26bb56 HTTP/2 Ensure default settings are correctly enforced and interfaces clarified
Motivation:
The responsibility for retaining the settings values and enforcing the settings constraints is spread out in different areas of the code and may be initialized with different values than the default specified in the RFC. This should not be allowed by default and interfaces which are responsible for maintaining/enforcing settings state should clearly indicate the restrictions that they should only be set by the codec upon receipt of a SETTINGS ACK frame.

Modifications:
- Encoder, Decoder, and the Headers Encoder/Decoder no longer expose public constructors that allow the default settings to be changed.
- Http2HeadersDecoder#maxHeaderSize() exists to provide some bound when headers/continuation frames are being aggregated. However this is roughly the same as SETTINGS_MAX_HEADER_LIST_SIZE (besides the 32 byte octet for each header field) and can be used instead of attempting to keep the two independent values in sync.
- Encoding headers now enforces SETTINGS_MAX_HEADER_LIST_SIZE at the octect level. Previously the header encoder compared the number of header key/value pairs against SETTINGS_MAX_HEADER_LIST_SIZE instead of the number of octets (plus 32 bytes overhead).
- DefaultHttp2ConnectionDecoder#onData calls shouldIgnoreHeadersOrDataFrame but may swallow exceptions from this method. This means a STREAM_RST frame may not be sent when it should for an unknown stream and thus violate the RFC. The exception is no longer swallowed.

Result:
Default settings state is enforced and interfaces related to settings state are clarified.

e94db103c9 Ensure flowController().writePendingBytes() is triggered when writing response in example
Motivation:

We called ctx.flush() which is not correct as it will not call flowController().writePendingBytes().

Modifications:

e3fbfe5641 HTTP/2 example upgrade refcnt bug
Motivation:
Http2ServerInitializer uses a SimpleChannelHandler in an attempt to ease putting an HttpObjectAggregator in the pipeline when no upgrade is attempted. However the message is double released because it is fired up the pipeline (which will be released) and also released by SimpleChannelHandler in a finally block.

Modifications:
- Retain the message if we fire it up the pipeline

Result:
HTTP/2 examples don't encounter a reference count error if no upgrade was attempted.

f375772ff0 Remove OSGi import of JCTools since it is shaded.
Motivation:

Since netty shaded JCTools the OSGi manifest no longer is correct. It claims to
have an optional import "org.jctools.queues;resolution:=optional,org.jctools.qu
eues.atomic;resolution:=optional,org.jctools.util;resolution:=optional"
However since it is shaded, this is no longer true.
This was noticed when making JCTools a real bundle and netty resolved it as
optional import.

Modifications:

Modify the generated manifest by no longer analyzing org.jctools for imports.
A manual setting of sun.misc as optional was required.

Result:

Netty OSGi bundle will no longer interfere with a JCTools bundle.

fa6b0e262e Support Unicode filenames and spaces in directory listing
Motivation:

The HTTP Static File Server seems to ignore filenames that doesn't contains only latin characters, but these days people wish to serve files in other languages, or even include some emojis in the filename. Although these files are not displayed on the directory listing, they are accessible by HTTP requests. This fix will make such files more visible.

Modifications:

I've changed the ALLOWED_FILE_NAME pattern to disallow only files that starts with underline, minus or a dot (such as .htaccess), and hide other "unsafe" filenames that may be used to trigger some security issues. Other filenames, including the space character are allowed.

I've also added charset encoding to the directory listing, because the browser default MAY be configured for ISO-8859-1 instead of UTF-8.

Result:

Directory listing will work for files that contains the space character, as well as other Unicode characters.

15222c084d Never expose user.dir to the web on directory listing
Motivation:

When Netty HTTP Static File Server does directory listing, it does expose the user.dir environment variable to the user. Although it doesn't a security issue, it is a bad practice to show it, and the user does expect to see the server virtual root instead, which is the absolute path as mentioned in the RFC.

Modifications:

the sendListing method receives a third argument, which is the requested URI, and this is what should be displayed on the page instead of the filesystem path.

Result:

The directory listing pages will show the virtual path as described in the URI and not the real filesystem path.

Removed fallback method

3a4d30df4e Make SocksServer example compatible with curl --socks5-hostname
Motivation:

Socks5 proxy supports resolve domain at the server side. When testing
with curl, the SocksServer in example package only works for proxy
request with IP, not with domain name (`--socks5` vs
`--socks5-hostname`). As curl is widely used, it should work with
the example provided.

Modifications:

Passing address and port to the Socks5CommandResponse, so that it
works for curl.

Result:

`curl --socks5-hostname` works as expected.
